To all whom it may concern.-

Be it known that I, JAMES F. LOWENHAUPT, a citizen of the United States, residing at Woodhaven, Queens county, and State of New York, have invented certain new and useful Improvements in Embossing-Machines, of which the'following is a specification.

My invention relates to the embossing of cardboard, paper, and flexible material generally, and particularly to the manufacture of what are known as card-mounts, consisting of embossed cards for the backing or mounting of photographic and other pictures and for analogous purposes. Heretofore these card-mounts have been embossed sinly, thus involving considerable time in their andling and manipulation and necessarily rendering them, relatively speaking, expensive.

The main object of my invention is to simplify and cheapen the manufacture of such card-mounts by providing suitable apparatus, whereby a whole sheet of cardboard may be accurately fed to and embossed by and between a series of rotatable dies and matrices to form any prescribed number of cardmounts in such manner that the operation maybe designated as practically continuous.

To this end the invention consists in the combination and arrangement of parts hereinafter described and claimed specifically.

Inthe accompanying drawings, Figure 1 is a plan of the apparatus; Fig. 2, afront elevation Fig. 3, a side elevation; Fig. 4, 'a vertical section upon plane of line 4 4, Fig. 1; Fig. 5, a vertical section upon plane of line 5 5,'Fig. 1. Fig. 6 is a sectional elevation on plane of line 6 6, Fig. 1. Fig. 7 is a detail view, upon an enlarged scale, of the cross-head and adjoining parts.

In the drawings, Arepresents the side members or standards of the framework united by cross-rods a.

P is the power-shaft, mounted in suitable bearings in the standards A and carrying the power-pulley p at one extremity and the pinion 19 at the other. The pinion p meshes with a gear I) upon the shaft B, journaled in the standards A, said gear I) in turn meshmg with a corresponding gear 0 upon the shaft 0, mounted adjustably on the side members A. The upper shaft C carries what may be designated as the die-drum D, While upon the lower shaft B the matrix-drum M is mounted.

R is a rock-shaft actuated by a cam or eccentric E upon the shaft B through the medium of the roller 1" and arm 7", said rockshaft R carrying the lever W, in the upper ends of which the cross-heads F are ful crumedthat is to say, each cross-head F is formed with a trunnion f, which fits in a bearing r formed inthe lever r for its reception. On the side of each cross-head F opposite to that on which the trunnion f is situated are studs f for engagement with bifurcated arms g, keyed to rock-shafts G, the opposite ends of which are journaled in slides H, mounted upon stationary ways 72. on either side of the machine. shafts G carry grippers g, the opposed ends of which are brought together by the rocking of the shafts G, pinching between them the sheet of cardboard to be fed to the cylinders D and M. Springs 1" are arranged to thrust the roller 1" against the cam E, so that when the depression 6 in the latter is reached the shaft R will be rocked, throwing the upper end of each lever r inward, the levers carrying with them the cross-heads F. As a result the studsf, acting on the bifurcated arms g, rock the shafts G, and thereby bring the grippers g together.

Motion is transmitted through the bifurcated arms 9 and rock-shaft G to the slides II to admit of the feed-thrust. The return of the roller 1* to the concentric portion of the cam E returns the slides and parts to their normal position with the gripper-fingers separated as at first. Previous to this action a sheet of card is fed in between the grippers g until its edges rest against registering shoulder t, which is a straight-edge formed upon the rock-bar I, fulcrumed between the standards AA and carrying an arm or projection i, which normally projects into the path of a roller d on the drum D, so that during the rotation of the cylinder the registering straightedge 1'. is tripped or depressed at the proper time to admit of the feeding of the edge of the sheet to the dies. This happens just prior to the forward movement of the grippers g hereinbefore described, the cam E being so timed with relation to the motion of the drum D as to effect this result. The forward motion of the grippers carries the edge of the cardboard into contact with the stop d on thecylinder D, which at this moment is central or on the vertical line between the axes of the two drums D and M, the dies pinching and carrying forward the sheet from this These rock- .point.

m, to admit of the protrusion of the stop at. The cardboard after being embossed by and between the die d and the matrix m passes to and between the slitters S, which consist of circular knives mounted on shafts s s, journaled in brackets a attached to the side standards A. The shafts s s are rotated by motion borrowed from the powershaft through the medium of the sprocket-chain j, which engages with the sprocket-wheels 12 upon the power-shaft P and with the sprocketwheel 8 upon one of the said slitter-shafts s, the two latter being geared together by gearwheels s 8 The slitters S serve as feeders and are adjustable laterally upon their shafts s, as are the grippers g for the purpose of varying their relation to the requirements of the work to be performed.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a machine for embossing, in combination with a cylindrical rotatable die and a cylindrical rotatable matrix, the cam E, rock-shaft R, levers r cross-head F, rockshafts G, grippers g, and slides H, for the purpose set forth.

2. In a machine for embossing, in combination with a cylindrical rotatable die and a cylindrical rotatable matrix, the cam E, springs r rock-shaft R, levers r cross-head F, rock-shafts G, grippers g, and slides H,- for the purpose set forth.

3. In a machine for embossing card-mounts, a cylindrical rotatable die and a cylindrical rotatable matrix, combined with feed mechanism adapted to forward the cardboard, means cooperative with a portion of said feed mechanism for returning the grippers thereof to their normal position, a registering shoulder, and means, operable prior to the forward'movement of the gri pers, for tripping said shoulder to permit 0 the feeding of the edge of the card to the dies.

4. In amachine for embossing card-mounts, a cylindrical rotatable die and a cylindrical rotatable matrix, combined with feed mechanism adapted to forward the cardboard, means cooperative with a portion of said feed mechanism for returning the grippers thereof to their normal position, a registering shoulder, means, operable prior to the forward movement of the grippers, for tripping said shoulder to permit of the feeding of the edge of the card to the dies, a rock-shaft carrying said shoulder and having a projection, and a roller carried by the die for cooperation with said projection.
